/* ============================================================================
   Vino — Design A: "Cupertino"
   Apple HIG purist. System font ramp, semantic surfaces, hairline separators,
   translucent materials, one tint colour (deep burgundy) used like iOS uses
   tint: for what you can touch, and nothing else.
   Drop-in replacement — every legacy class name is preserved.
